When a video advert is placed in the middle of a thread, once I scroll down far enough to see it and it starts playing, I can't read the rest of the thread. When I try to scroll further down, or even back up, the page jumps back to the ad. It's super annoying and makes some threads un-readable. I understand the need for ads, but can we have ads that work properly and don't render the threads useless?

BTW if its helpful. I'm using Chrome on windows XP or Windows 7 professional 32 bit. (does the same thing on both of my computers)
